Following his success, Team Scorpion will have to infiltrate a high-end car smuggling operation that is about to ship bioweapons to America.

In episode 18, Team Scorpion will also work closely with a slew of new characters including "The Price is Right" host Drew Carey and Announcer George Gray.

Other guest stars include Eric Roberts and Joely Fisher, and the two will play the role of Agent Cabe Gallo's (Robert Patrick) friends.

Meanwhile, fans are awaiting updates regarding Walter and Paige's (Katharine McPhee) relationship.

In "Adaptation," Walter finally found out that Toby (Eddie Kaye Thomas) and Happy (Jadyn Wong) are in a relationship.

Walter's initial reaction is quite negative especially after he previously made it clear to the members of Team Scorpion that fraternization is not allowed.

However, Toby and Happy tried their best to prove to Walter that their relationship will not affect their work with the team.

Unfortunately, this wasn't the case because the new couple just ended up fighting at one point.

On the other hand, Toby and Happy's relationship can make Walter realize that acting on his feelings for Paige is not such a bad thing.

In an upcoming episode, Walter will attempt to invite Paige out on a date only to be rejected because of Scott Porter's character Tim Armstrong.

According to TV Line, the "Hart of Dixie" alum will play the role of a Navy SEAL who was injured during his deployment.

Tim will become Cabe's newest trainee courtesy of the Homeland Security, and Walter may not necessarily approve of his involvement in the investigations.

Since Walter knows that Tim is smart and good-looking, the lead character will be threatened by him.

To add to his worry, Paige will immediately be interested in getting to know Tim, and the latter will also be interested in getting to know her better.

"Scorpion" season 2, episode 18 will air on CBS on Feb. 29 at 9 p.m. ET.
